Jérémie Unterberger
I am currently assistant professor at the maths institute IECL (Institut Elie Cartan de Lorraine), in the Probability and Statistics team.
My usual research interests include rigorous renormalization techniques, mathematical physics, statistical physics, stochastic calculus, energy transition and foresight studies.
Main current research subjects:
○ Origin of life : from chemistry to biology through a systemic approach
○ Climate and energy transition : foresight studies for the 21st century
Projects:
○ PEPR Origins (2022-29): from planet formation to origin of life
○ ERC AbioEvo (2020-25) : conditions for the
emergence of evolution during abiogenesis
Former projects:
○ METALORIGIN (2023, financement INSU): le métal des météorites, moteur de l’évolution abiotique dela matière organique complexe des surfaces planétaires primitives
○ ANR SINGULAR (2017-2021) on singular stochastic PDEs and renormalization
○ GDR RENORM on algebraic, analytic and geometric aspects of renormalization
